Continuum Damage Mechanics Modeling Of High-Temperature Flaw Propagation: Application To Creep Crack Growth In 316H Standardized Specimens And Nuclear Reactor Components
Predicting creep crack growth (CCG) of flaws found during operation in high-temperature alloy components is essential for assessing the remaining lifetime of those components. While defect assessment procedures are available for this purpose in design codes, these are limited in their range of applicability. This study assesses the application of a local damage-based finite-element methodology […]
Engineering-scale Modeling of High-Temperature Creep and Creep Crack Growth in Alloy 316H
This document demonstrates completion of the goals described in the technical narrative of the De- partment of Energy’s Industry Funding Opportunity Announcement (iFOA) project entitled “Modeling and Simulation Development Pathways to Accelerating KP-FHR Licensing,” which relates to the development and demonstration of capabilities for conducting engineering-scale simulations of Alloy 316H components under high-temperature conditions. This […]
